Abstract
Description
The present invention relates to a system for laying out shaped objects such as geometrical objects and the like in a specific space, and in particular, to a system for automatically creating a layout plan under various restrictive conditions.
In an ordinary case, a layout design is generated through the man-machine conventional processing for laying out geometric objects. Such layout design forms a subject matter of the present invention.
For a conventional system applied to the above-stated purpose, the human designer for creating a layout plan is required to memorize various restriction about interrelationships between such objects in advance.
Recently, a system has been developed by an artificial intelligence study group in the United States of America in which computer parts are automatically arranged in the space inside a computer frame (R1 : the name of such a system developed by J. Mcdermott at C.M.U. see HAND-BOOK OF ARTIFICIAL INTELLIGENCE by E. Feigenbaum).
This system possesses a set of rules for determining the places at which computer parts are to be laid out and the layout system uses an appropriate rule depending on the progress of the designing work.
In this system, however, the candidate places of the parts to be laid out must be known in advance.
The best layout (place and direction) for placing an object in a specific space is determined depending on various information such as about objects already existing in the space and their locations and associated objects other than those placed in the space and their locations.
Consequently, a deterministic algorithm or procedure for placing such objects and the like in a space cannot be easily specified in advance.
For a placement problem for arranging objects in a space, the combinational optimization method has been adopted heretofore. When applying this method to a placement problem, the layout designer has usually approached the final solution by optimizing an objective function representing a parameter in this problem, for example, the layout area.
This method, however, is not preferably applied to a problem which handles information other than the element to be obtained through an object function, for example, information that reflects a layout of an object to be placed by conforming to a positional relationship to another object specified as the reference information such things as "the front line placed object should be in line". Consequently, it has been difficult to automatically generate a layout plan similar to one designed based on various information by the expert designer.
It is therefore an object of this invention to provide an automatic layout planner system for generating an appropriate layout design under a condition in which the placement of geometric objects cannot be specified in advance.
In order to achieve this object of the present invention, there is provided an automatic layout planner system composed of an inference engine and a knowledge base section which contains various knowledge to be utilized under various conditions encountered in the processing of an automatic layout for generating a layout design.
The objects and features of the present invention will become more apparent from the consideration of the following detailed description taken in conjunction with the accompanying drawings.
FIG. 1 is a schematic block diagram of an automatic layout planner system according to an embodiment of the present invention.
FIG. 2 is a processing flowchart for explaining the rule interpreter 115 of FIG. 1 in accordance with the embodiment of the present invention.
An embodiment of the present invention will be described in detail hereinbelow.
FIG. 1 illustrates the basic configuration of an automatic layout planner according to an embodiment of the present invention. Abody 100 of the automatic layout planner comprises aknowledge base 110 containing various information items such as rules for specifying an appropriate area where devices may be placed, figures of a device, and functions for checking whether or not the restrictions imposed on the placement are satisfied. A rule interpreter 115 of FIG. 1 is utilized to select a proper rule from the knowledge base 110 (125) by referring to adata structure 120 representing the current layout state (130). The selected rule is used to collate the content of the data structure 120 (135) or to write an information item therein. When an information item in thedata structure 120 is specified to be displayed (145) by use of a function stored in theknowledge base 110, the information item is displayed on agraphic display unit 105. In this example,display 105 shows aspace 155 in which objects should be placed (the boundary of a computer room in this example) and shapedobjects 160 such as a central processing unit and magnetic tape units in this example. Thegraphic display unit 105 is also used by a human designer to input information (150) to start the system, to revise the generated layout plan, and so on. In this embodiment, the system is implemented by use of the list processing (LISP) language.
Table 1 lists a part of the information stored in thedata structure 120. A listing section 210 contains a data structure of the conditions to be satisfied when objects are placed. A system name, "Computer System for Design Automation Department, 211" has a generalized concept "SYSTEM" (212), and a plurality of objects (213) from L1 to L14 are assigned as units to be placed in a room having a name "computer machine room 1, 214" under eleven restrictive conditions (215) from C1 to C11 for the placement.
A listing section 220 of Table 1 defines the real shape of room 1 listed above. The room 1 has a generalized concept and has a shape specified by "RECT" for a rectangle whose longitudinal and transversal lengths are 11750 and 9500, respectively (222). Moreover, this listing section 220 contains the scale (223) for displaying the room on thegraphic display unit 105 of FIG. 1. origin of the room (224), name of the door (225), name of the column in the room (226), origin of the free access area (227), and size of unit free access (228). A free access indicates a tile of the floor in the room and is ordinarily a square. When placing a machine, free accesses are removed before installing cables of the machine. The free access information is stored because the free access range and unit of the room must be checked for the placement.
A listing section 230 of Table 1 lists information about L1 specified in the layout unit group (213). The L1 has a generalized concept "object to be laid out, 231" and a machine name "H-8A60-01" (232). The pattern (plan view of the object L1) necessary for creating a layout plan is specified as "CPU6H30" (233), the L1 has a mnemonic name "CPU" (central processing unit, 234), and a "CPU" layout rule must be used to place the L1 (235).
A listing section 240 of Table 1 contains the data for the C10 listed in the restrictions (215). A description (241) indicates that the C10 has a generalized concept "far away, 241" and that machines such as "DISK", "CCP", "CPU", and "PDU" are to be placed far away from the door of the room (243), where the minimum distance from the door is three meters (244).
A listing section 250 of Table 1 indicates the current state of layout planning for placing an object OP4 in the room. Line 251 means that the data OP4 has a generalized concept "OP" (operation, 251) and "OP4" relates to the object "L1" (252). Furthermore, the position in the room is set by the user ("USER") from thegraphic display unit 105 of FIG. 1 (253), the object is placed in room 1 (254), its shape is specified as "H-8A60-01" (255), and the maintenance area (required for the maintenance of this mahcine, for example, an area to be used to open a door) has its origin at a point (-800, -800) on the coordinate attached to the object to be arranged and is set with an angle of 0 degree on the coordinate attached to the room. The shape of the maintenance area is a rectangle ("RECT") whose size is indicated as 3860×2300 (256). This section 250 also contains information such as that the origin of OP4 is at a point (10102, 6417) on the coordinate attached to the room and the layout angle is -90°.
A listing section 260 of Table 1 specifies the current state of layout planning and causes the display of Computer System For Design Automation Department 211 (262) on the screen of thegraphic display unit 105 of FIG. 1 in which the data (shape of the room and names of the objects to be placed) on the problem has been entered as the premise for generating the layout design (263).
Next, the contents of theknowledge base 110 shown in FIG. 1 will be described in conjunction with Table 2.
A listing section 300 contains a group of rules indicating the procedures for generating the layout design. A rule comprises a condition section and a procedure section. The condition section involves a condition of occurrence such as an "if" condition. The procedure section is the action to be taken such as the response to taken in satisfying an "if" condition. A rule in line 301, for example, specifies to stop generating the layout design if a data item, "problem already solved" is given as a data assigned with a reference number 260 in thedata structure 120 of FIG. 1. A rule in line 302 means that the layout designing is to be initiated if "problem already entered" appears.
A rule in line 310 specifies to delete (DELETES) a data item, "problem being solved" from the data structure 260 listed in Table 1 and to execute some other processing if the state, "problem being solved" is changed to "end, 311".
A listing section 320 in Table 2 is an example of object layout rule and specifies to execute the layout planning by use of the using input (USER) if there does not exist a rule matching with the condition (the parameters (>X>Y>Z) contained in the IF clause in line 321 of Table 1 means that the rule invocation key X, Y, Z are variable which can match any three dimensional date so that the rule can be invoked whenever other rules cannot match current status of the data structure described by three dimensional data items and so the user input is preferred to continue problem solving.
A listing section 330 is a group of rules for specifying the locations of objects to be placed in which line 331 indicates to consider a plan to place a floppy disk (FD) unit in the range of space satisfying the condition "on the right-hand side of . M 2 M two meters far" with respect to a card reader if the card reader (CR) and a console display (CD) unit have been placed by satisfying the relationships specified by the parameters such as "to the right of . facing left".
Lines 340 to 370 of Table 2 are the functions contained in the rules described in conjunction with Table 2 (1). These lines 340-370 form a part of theknowledge base 110. Line 370, for example, is a function to be used to shift a position of an object layed out if the allocated area is insufficient for the object.
Table 3 is a part of the contents of the rule interpreter 115 shown in FIG. 1. Line 410 specifies a rule group control function for checking information stored in thedata structure 120 of FIG. 1 to select a rule group stored in theknowledge base 110 of FIG. 1. (For example, the listing sections 300, 310, 320, and 330 of Table 2 each form a rule group consisting of a plurality of rules.) Line 420 is a function for calling a rule from the rule group specified above, while line 430 indicates a function which executes the right side of the invoked rule in order to generate a layout plan and associated data and to store them in thedata structure 120 of FIG. 1.
The operations of the embodiment will be described by referring to FIG. 2 in accordance with the present invention.
In step 505, the layout object, room information, and the like are entered to generate the data structures such as those specified by the listing sections 210, 220, 230, and 240. If it is found instep 510 that all devices have already been laid out, control is passed to step 560 in which the processing is terminated by regarding that all devices have been laid out; otherwise, the processing proceeds to step 515 is order to select a device to be laid out. Instep 520, the system checks the layout rules such as those specified by the listing sections 320 and 330 to determine an applicable layout rule by using functions such as those listed in the lines 340, 345, and 350. If such an applicable item is missing, control is passed to step 565 in which the processing is terminated without determining the place for the device which could not be laid out; otherwise, steps 525 and 530 are sequentially processed to check each solution and to judge whether or not restrictions such as that defined by the listing section 240 are satisfied by using functions, for example, those listing in lines 370 and 380. If a solution satisfying the restrictions is found instep 535, the solution is selected instep 540 and the layout state is updated instep 545, then control is passed to step 510; otherwise, the processing proceeds to step 550 in which each solution is checked under conditions that the parallel displacement of the objects already laid out is allowed so as to satisfy the restrictive conditions. If a solution satisfying the restrictions is found instep 555, control is passed to step 540; otherwise, the processing proceeds to step 565 in which the processing is terminated.
As can be seen from the descriptions hereabove, the automatic layout planner system according to the present embodiment composed of a knowledge base comprising rules for processing various conditions which happens during the layout design process and the inference engine which calls an appropriate rule therefrom depending on a current condition; consequently, this system can be effectively applied to solve a problem, for example, a layout planning for which the processing procedures cannot be clearly defined in advance.
The capability for configuring a layout and for generating a layout plan can also be improved by employing additional rules.
